you can use gridview.rowdatabound event event.

then find linkbutton using findcontrol method.

public class animal {     public int rownumber { get; set; }     public string name { get; set; } }  protected void page_load(object sender, eventargs e) {     if (!ispostback)     {         gridview1.datasource = new list<animal>         {             new animal {rownumber = 1, name = "one"},             new animal {rownumber = 2, name = "two"},             new animal {rownumber = 3, name = "three"},             new animal {rownumber = 4, name = "four"},         };         gridview1.databind();     } }  private int _counter;  protected void gridview1_rowdatabound(object sender, gridviewroweventargs e) {     if (e.row.rowtype == datacontrolrowtype.datarow)     {         if (_counter == 0)         {             var linkbutton = e.row.findcontrol("deleteitemsgridrowbutton")                  linkbutton;             linkbutton.visible = false;             _counter++;         }     }  }
